Aero

Aero is a harpy and the first Autana that Eita Touga met, who is asked to help her save her world, taking him to Re-verse and becoming his first of one of his traveling companions. She is the first to fuse with his gauntlet, providing him with extreme speed and strength. Aero is quite absent minded and distracted by shiny objects. She is also a closet Ninja Otaku and has an extensive collection of memorabilia dedicated to ninjitsu.
